I only have one motorcycle. The '75 GL1000 trike.
It has an engine guard that tightly blocks the #s 1 and 2 synchronizer ports.
Here is my remedy. Bought the four 90degree fittings from a seller on ebay. China. The nuts and red vinyl caps from a hardware store.

In addition to serving as a synchronizer hose hook up, they also provide a little entertainment.
If I shut the warm engine down with the key switch, then accidentally turn the key on and back off again, any cylinder with an open intake valve will abruptly pop the fitting''s red vinyl cap off. Gone. Haven't found one yet!
I got wise and keep a small supply in the tool tray.
Have also had a few inquiries about their purpose.
That's where the nitrous is injected....
